Why is this medicine prescribed?
Diclofenac ophthalmic solution is used to treat eye pain, redness, and swelling in patients who are recovering from cataract surgery (procedure to treat clouding of the lens in the eye). Diclofenac ophthalmic solution is also used to temporarily relieve eye pain and sensitivity to light in patients who are recovering from corneal refractive surgery (surgery to improve vision). Diclofenac is in a class of medications called nonsteroidal anti-inflammatory drugs. It works by stopping the production of certain natural substances that cause pain and swelling.
Are there other uses for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Ophthalmic diclofenac comes as a solution (liquid) to instill in the eyes. When diclofenac eye drops are used by patients recovering from cataract surgery, they are usually instilled 4 times a day beginning 24 hours after surgery and continuing for 2 weeks after surgery. When diclofenac eye drops are used by patients undergoing corneal refractive surgery, they are usually instilled one hour before the surgery, 15 minutes after the surgery, and then four times a day for up to 3 days. Use diclofenac eye drops at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use diclofenac eye drops exactly as directed. Do not use more or less of them or use them more often than prescribed by your doctor.
To use the eye drops, follow these steps:
- Wash your hands thoroughly with soap and water.
- Check the dropper tip to make sure that it is not chipped or cracked.
- Avoid touching the dropper tip against your eye or anything else; eyedrops and droppers must be kept clean.
- While tilting your head back, pull down the lower lid of your eye with your index finger to form a pocket.
- Hold the dropper (tip down) with the other hand, as close to the eye as possible without touching it.
- Brace the remaining fingers of that hand against your face.
- While looking up, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. Remove your index finger from the lower eyelid.
- Close your eye for 2 to 3 minutes and tip your head down as though looking at the floor. Try not to blink or squeeze your eyelids.
- Place a finger on the tear duct and apply gentle pressure.
- Wipe any excess liquid from your face with a tissue.
- If you are to use more than one drop in the same eye, wait at least 5 minutes before instilling the next drop.
- Replace and tighten the cap on the dropper bottle. Do not wipe or rinse the dropper tip.
- Wash your hands to remove any medication.
What special precautions should I follow?
Before using diclofenac eye drops,
- tell your doctor and pharmacist if you are allergic to diclofenac; aspirin or other NSAIDs such as nepafenac (Nevanac), ibuprofen (Advil, Motrin), naproxen (Aleve, Naprosyn), or tolmetin (Tolectin); any other medications, or any of the ingredients in diclofenac eye drops. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: anticoagulants ('blood thinners') such as warfarin (Coumadin); aspirin and other NSAIDs such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn); and corticosteroid eye drops such as dexamethasone (Maxidex), fluorometholone (FML), hydrocortisone (in Cortisporin), loteprednol (Alrex, Lotemax), medrysone (HMS), prednisolone (Pred Mild), and rimexolone (Vexol). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have or have ever had diabetes, rheumatoid arthritis (arthritis caused by swelling of the lining of the joints), dry eye disease or any eye problem other than cataracts, or any condition that causes you to bleed easily.
- tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, you plan to become pregnant, or you are breast-feeding. If you become pregnant while using diclofenac eye drops, call your doctor.
- tell your doctor if you wear soft contact lenses. Your doctor may tell you that you should not wear your contact lenses during your treatment with diclofenac eye drops.
What special dietary instructions should I follow?
Unless your doctor tells you otherwise, continue your normal diet.
What should I do if I forget to take a dose?
Instill the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not instill extra eye drops to make up for a missed dose.
What should I do in case of overdose?
If someone swallows diclofenac eye drops, call your local poison control center at 1-800-222-1222. Give the victim plenty of liquids to drink. If the victim has collapsed or is not breathing, call local emergency services at 911.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http://goo.gl/c4Rm4p ) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
What other information should I know?

You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
